Aurélie Franck is a mezzo-soprano with a light timbre and a preference for working in the fields of Baroque and contemporary music. She has worked with important vocal parts in the music of composers like Claude Ledoux and Thomas Jennefelt, as well as opera roles in works of John Adams and Philip Glass. In September 2014 Aurélie had her solo debut in the Berliner Philharmonie under the direction of Iván Fischer.

The duo has collaborated closely on the programme Fragments, which consists of works of two belgian composers, written specially for them. Claude Ledoux’s Notizen-Fragmente sets youthful texts by Rainer Maria Rilke, while Jean-Pierre Deleuze's song-cycle Voici l’absence – Cinq déplorations en antiphonie sets texts by Baschô, Jacques Crickillon and Henri de Montherlant.
